The following are examples of an incident that would be considered a flood.
• River flood - an ingress of water from a river or other watercourse bursting its banks
• Coastal flood - an ingress of water from the sea
• Flash flooding - an ingress of water caused by heavy localised rainfall over a short period which cannot be soaked up or drained away leading to the surface run off of water over land. It may also be caused by the failure of drainage systems to cope with the amount of rainfall. Flash flooding is difficult to predict and can arise anywhere, for example, in a built up urban area away from a river.

Important - Incidents such as a leaking pipe, shower or washing machine are considered escape of water and not floods.
